School districts in Alaska

Alaska is unusual: only 8.2% of its populated ZIP Code areas are served by more than one school district, where the national figure is 53%. Districts here are large enough, or ZIP Code areas small enough, that the two mostly line up — Anchorage alone covers 118,640 homes. That makes the 20 areas that do cross a line worth naming rather than assuming. Its most divided ZIP Code area, 99760, is split between 4 districts for elementary grades alone. The two districts that share the most ZIP Codes here are Copper River and Alaska Gateway, in 2 of them. Counted by homes rather than by ZIP Code area, 7.9% of the state's housing sits in a ZIP Code that more than one district serves.

How many school districts are in Alaska?

52: the Census boundary file draws 52 school districts in Alaska that reach at least one ZIP Code area with homes, 52 unified, 0 elementary and 0 secondary. A ZIP Code here can sit in more than one of them, which is why a school district lookup by ZIP Code for Alaska lists them all: find your school district by ZIP code.

ZIP Codes and district lines mostly agree here

The state sits well below the national rate of 53%. Anchorage alone covers 118,640 homes, and districts that size swallow whole postal areas rather than splitting them. Where a ZIP Code area here does cross a line, it is worth checking precisely because it is unusual: 20 of the 243 do.

The most divided ZIP Code area in Alaska

ZIP Code area 99760 holds 668 homes, and 4 districts each take a meaningful share of them for elementary grades — Yukon-Koyukuk first at 43%, then Nenana City. A lookup that names the first is describing that share of the homes and silently not the 380 homes that remain.

Grade schoolYukon-Koyukuk School District43%288 of 668 homes

High schoolYukon-Koyukuk School District43%288 of 668 homes

Each percentage here is a share of the 668 homes counted in ZIP Code 99760, not the chance that any one address is in that district. Enrollment follows the street: two houses on opposite sides of the same road can be in different districts, and only the district office can say which.

Every track below is 35 cells long and stands for all 668 homes counted in ZIP Code 99760, so one cell is 19 homes, rounded to the nearest whole cell. Cells lit solid are the homes one district holds, and the unlit cells are the homes held by the other districts in the same list.

Denali Borough School District116 of 668 homes17%

For grade school, an answer of one district name would be wrong for 380 of the 668 here.

Where a single district name still works in Alaska

Across the 243 ZIP Code areas in Alaska with homes in them, an answer of one district name misses 3,444 of the 323,782 homes they hold. That is 1.1% of the state, and in 219 of the areas the largest district for the early grades holds every home counted: this is a state where the familiar answer is usually the right one, and the areas below are where it is not.

In ZIP Code 99588 · Mendeltna, Alaska the largest district for grade school is Copper River, and naming it alone misses 629 of the 1,312 homes counted there. For grade school the rest is 629 homes with Matanuska-Susitna Borough.

In ZIP Code 99921 · Hollis, Alaska the largest district for grade school is Southeast Island, and naming it alone misses 512 of the 1,060 homes counted there. For grade school the rest is 512 homes with Craig City.

In ZIP Code 99576 · Dillingham, Alaska the largest district for grade school is Dillingham City, and naming it alone misses 406 of the 1,400 homes counted there. For grade school the rest is 406 homes with Southwest Region.

Where a ZIP Code here names more than one district

Of the 243 ZIP Code areas in Alaska that the federal file names a district for, 20 name more than one school district. These are the 12 with the most, starting at 4 districts in one postal area: Healy, Deltana and Lime Village. No district in Alaska has a page of its own here yet — the corpus is chosen by the homes a district covers, and the districts in this state are small — so each row below opens the full answer for that ZIP Code in the lookup instead.

What to do next

Ask the district office to confirm your street address: look on its site for a school locator, a find my school tool or an attendance zone map, or call the office.

A ZIP Code is a set of mail delivery routes, not a boundary: 20 of the 243 ZIP Code areas in Alaska with a district named for them are served by more than one school district, and the line between two of them runs along streets. Only the district can say which side of that line an address is on.

District websites and phone numbers here come from the NCES Common Core of Data directory, 2024-25 school year, filed under the same district ID as the Census boundary files. Where it lists no usable website, none is printed rather than guessed.

If a house purchase depends on the answer, ask the district itself for written confirmation of that exact address. A listing is not a district record, and neither is this page.

Where these numbers come from

The homes were counted in the 2020 Census and the district lines are the 2026 boundary file, so a fast-growing area may have changed since; ZIP Codes here are the Census Bureau's ZIP Code Tabulation Areas; a share is a share of homes, not the chance that one address is in a district; and a district is not a school attendance zone. Every source, file and caveat is on the method page.
